Therefore, it isfavorable for providing the main converging ability of the incidentlight in the photographing optical lens assembly, so that the volume ofthe photographing optical lens assembly can be effectively reduced tosatisfy the demand of compact size.

The second lens element can have negative refractive power, and can havean object-side surface being convex in a paraxial region thereof and animage-side surface being concave in a paraxial region thereof.Therefore, focusing positions of lights with different wavelengths canbe balanced so as to avoid the image overlay, and the sphericalaberration can be reduced by a coordinating configuration with the firstlens element.

The fourth lens element can have an object-side surface being concave ina paraxial region thereof and an image-side surface being convex in aparaxial region thereof. Therefore, it is favorable for correcting theastigmatism of the photographing optical lens assembly by balancing thelight path in the tangential direction and the sagittal direction.Furthermore, at least one of the object-side surface and the image-sidesurface of the fourth lens element includes at least one inflectionpoint, so that aberrations in an off-axial region thereof can becorrected.

Furthermore, atleast one of the object-side surface and the image-side surface of thesixth lens element includes at least one inflection point. Hence, it isfavorable for correcting aberrations in the off-axial region andreducing the back focal length so as to balance between the imagequality and the physical size of the lens assembly.

The seventh lens element can have positive refractive power and can havean image-side surface being convex in a paraxial region thereof.Therefore, the symmetrical structure of the photographing optical lensassembly can be formed by the seventh lens element and the first lenselement for improving the image quality.

When a focal length of the photographing optical lens assembly is f, anda curvature radius of the object-side surface of the first lens elementis R1, the following condition is satisfied: 2.85<f/R1.

When the lens elements are made of glass materials, thedistribution of the refractive power of the photographing optical lensassembly may be more flexible to design. When the lens elements are madeof plastic materials, manufacturing costs can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than a spherical surface so as to have more controllablevariables for eliminating aberrations thereof, and to further decreasethe required amount of lens elements in the photographing optical lensassembly. Therefore, the total track length of the photographing opticallens assembly can also be reduced.
